　　What material is good for plastic milk bottles

　　Since the common feature of plastic milk bottles is light weight and resistance to falling, and the above four materials are safe and free of bisphenol A, if you want to know which material is good, you can check the transparency, wear resistance, high temperature resistance, cleaning difficulty, replacement Time, price, etc. to compare.

　　Transparency and abrasion resistance: PPSU and PA are the best

　　Compared with glass milk bottles, the disadvantage of plastic milk bottles is poor transparency and easy wear and tear. After a long time of use, the surface will be fogged, making it impossible to clearly observe the milk in the bottle, and it is not easy to clean. However, with the advancement of technology, the transparency and wear resistance of PPSU and PA baby bottles have been comparable to glass baby bottles.

　　PPSU generally has a light golden yellow color, but it has high transparency and is not easy to wear. PA is a colorless and transparent material, and the transparency is also very good. The PP material has a light milky white color, and the transparency is relatively poor. The transparency of PES is between PP and PPSU.

　　High temperature resistance: can withstand high temperature above 100 ℃

　　What kind of material is good for plastic milk bottles? Since the milk bottle needs to be sterilized at high temperature, it is generally required to have better high temperature resistance characteristics. PP milk bottles can generally withstand high temperature of 120 °C, PPSU milk bottles can withstand high temperature of 180 °C, PES milk bottles can also withstand high temperature of 180 °C, and PA milk bottles can withstand high temperature of 220 °C.

　　Ease of cleaning: The material has little to do with the shape of the bottle

　　Plastic bottles are generally harder to clean than glass bottles, so a bottle brush is essential. From the practical point of view, the cleaning difficulty of these four materials is similar. The key is to look at the shape of the bottle. If the shape of the bottle is more peculiar and has many dead ends, it is generally not easy to clean. The product.

　　Replacement time: the more transparent and wear-resistant, the longer the use time

　　There are different opinions about the replacement time of plastic milk bottles. Some businesses say that the milk bottle can be replaced in 3 months, while others think that it will be replaced in half a year. However, as a consumer, it is too extravagant to replace the baby bottle every 3 months. Wait until the bottle is nebulized before changing it. From this point of view, if the milk bottle has high transparency and is more wear-resistant, can it be used for a long time, that is to say, the use time of PPSU, PA and PES is usually longer than that of PP. Of course, this is also related to personal habits.
